AI Investment Guru Leopold Aschenbrenner Returns to Investment Arena, Invests $500 Million in Chip Manufacturing Startup Source Foundry
TechFlow News, August 8, according to Bloomberg citing sources familiar with the matter, 25-year-old AI investor and former OpenAI researcher Leopold Aschenbrenner re-entered the investment market after his hedge fund Situational Awareness faced liquidity pressure, and made a significant investment in a Sequoia Capital-backed private chip manufacturing startup.
It is reported that the company is Source Foundry. Leopold Aschenbrenner had previously invested $100 million in Source Foundry, and after adding another $400 million this time, his cumulative investment in the company reached $500 million.
The investment was completed this Tuesday and is one of the significant actions taken by Aschenbrenner after the Situational Awareness fund faced financial pressure due to margin calls from multiple Wall Street lenders.
Source Foundry was founded in 2025 and is headquartered in San Francisco, co-founded by Stanford material scientists Abdulmalik Obaid and Joe Burg.
The company aims to challenge the current extreme ultraviolet (EUV) lithography technology system dominated by ASML and attempts to resolve the contradiction between the rapid growth in AI computing power demand and the insufficient expansion speed of traditional chip manufacturing capacity.
